LUBRICATING SYSTEM.

Application filed. December 5, 1923. Serial No. e-r'aem'.

T all whom, it may concern:

Be it known that I, GEORGE R. Smcmsr,

.a citizen of the United States, residing at v Port Huron, county of St. Clair, State of Michigan, have invented a certain new and useful Improvement in Lubricating Sysparts.

l6DflS,.21l1d declare the following to be a full clear, and exact description of the same, such will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings. which form a part of this specification. I

My invention relates to improvements in vehicle chassis lubrication.

In'the lubrication of a vehicle chassis it gins heretofore'been a-common practice to provide oilcups'or gre'asecups for each part to be lubricated. These cups are kept filled with lubricant adapted todis'charg'e to the wearing parts. In many instances the lubricant was applied directly to the wearing Lubrication has also been accoma 1 a lphshed by providing" a lubrioant'storage receptacle, frequently disposed in proximity to the engine, having a separate conduit leading therefrom to each part to be lubri-.

cated. A pumpwas providcd, driven either from the engine or operated manually, by means of'which lubricant was drawn from the storage receptacle and forced through the conduits leading to the respective parts to be lubricated.

The last-named systemwas highly expensive and subject to considerablemechanical difli'culty and breakage. The first-mentioned system, which is in almost universal use, requires constant attention and is, therefore,

much neglectedand productive of a great deal of annoyance.

I provide a pumping device associated with each'of a selected number of conveniently and pivotally disposed spring shackles,

which pumping device communicates witha' -plurality of parts to he lubricated;which parts are grouped about the particularshackle: to distribute lubricant-to such parts. This pumping device is so constructed and operativcly connected with, theshackleand the parts to which the shackle is attached as to be operated by the movement of the shackle relative Qsuch partto discharge lulu'icant'un'dcr pressure to the shackle and to the. parts grouped about the shackle to be lubrlcated.

h bited in 1.

-An important feature is the provision of a lubricant distributing device consisting of a container for lubricant and an impeller associated with a shackle and a part to which the shackle is ivoted to be actuated by the movement of. t e shackle relative such part to lubricate the shackle by forcing lubricant under pressure thereto.

In the drawings, Figure 1 is a. plan View of an automobile chassis equipped with my invention.

In Fig. 1, I have indicated an automobile chassis in plan having side frame members mechanism comprises a lubricantcontainer. and an impeller connected with the shackle to be actuated by the movement thereof.

Each shackle, using the term in' the broad general sense, comprises side members ways as having outlets leading to the wearing surface of the bolts to lubricate the bolts.

My pumping device is attached to one side of the shackle and is here shown, as secured to the ends of the two shackle bolts by screwthreaded couplings '26. Each pumping mechanism comprises end pieces 27 between which is supported a tubular section 28 and seating in annular recesses in opposite faces of the end pieces upon su1table gaskets 29. The two end pieces are heldtogether by a bolt 30 which clamps the end pieces securely against both ends of the tubular section 28. I have shown this container as consisting of a glass tubular section 28 enclosed witlnn a metal casing 31 cut away at 32 to indicate the lubricant content of the container. This tubular member serves as a lubricant carrying receptacle and is of suitable size to carry the amount of lubricant desired.

My improved pumping mechanism comprises a pump chamber 33 which is formed in one of the end pieces 27 and communicates with the container by means of the passage way 34 to receive lubricant therefrom. A.

lunger 35 is disposed in the pump chamber iield outwardly by means of a spring 3-6 and a packing nut 37 1s provided to make atIght joint with the plunger. This pump chamber has a discharge opening 38 normally closed by a check valve 39 held in position by a spring 40, which openin 38 leads to the secondary chamber 41. This'chamber 41 has a discharge 42 through a suitable packing to the interior of the tubular coupling 26 and therefrom to the passageway 24 in the shackle bolt.- i

In Fig. 9, I have shown, in section, a device such as illustrated in diagram in Fig. 5, in which the outlet from the chamber 41 is by way of two branches one leading to each shackle bolt and in such construction a tube 43 leads from an outlet 44 from the chamber 41. This tube extends to the upper end piece 27 which is cored out at 45 to con'iii'iunicate with the l'lll')lllill"(lfill{lllllg 26 to carry lubricant to the upper shackle bolt."

In this construction thepassageway through each shackle bolt turns to discharge at the outer wearing surface of the bolt and there is no return of the lubricant to the receptacle.

In Fig. 6, I have shown in diagram a circulating system provided with outlets for discharge of lubricant to the wearing parts and providing for the return of lubricant to the container and the circulation of lubri' cant through the system, and in such con-- struction the tube 4-1-3 and opening ll s omitted and the lubricant flows in the direction of the arrows, and passageway 24 is cored out through a side piece 20 to prm vide for the 'passage of lubricant from one bolt to the other.

To operate the plunger 3:) different types of mechanism may be provided adapted to be actuated by the movement of the shackle. In Figs. 3, 4, 8 and 11., I show the lower end piece 37 provided with an angular support 46 which serves as a bearing for a pin 47 to one end of which pin is secured a lever arm 48, the outer end of which arm carries a roller 49 that is adapted to ride on the upper surface ofthc spring 18. On the opposite end of the pin 47 is mounted a lever arm 50 which with the lever arm i8 and the pin 47 forms what corresponds to a bell crank lever. The lever arm 50 carries an adjustable stop 51 which impacts the end of the plunger 35 to drive the same inwardly against the resistance of spring 36. The swinging movement of the shackle causes the spring 18 to rise and fall, which. through the roller 49, lever arm 48, pin 47. lever arm 50 and stop 51, forces the plunger 35 inwardly against the resistance of spring 36. Therefore, the rise and fall of the spring produces a pumping action which draws lubricant from the container into the pump chamber and forces it from the pump chain-- her, past the ball and check valve 39 to parts to be lubricated. By this means it is possible to force lubricant to parts desired and to develop sufficient pressure to overcome resistance offered to the passage of the lubr lcant by encrustation orfouling of the passageways through which the lubricant must flow.

I show in Fig. 7 a modified form of coin structlon for producing the pumping action.

In this construction I, pivot to the bracket 46 by- 'n'ieans of a pin 53 a lever ,arm This lever arm is shown as extending above and below the pivot point. At the --l()W0] end it is connected by link 54with tlledramc member 15. Swinging movement of the shacklecauscs the lever to oscillate about its pivot point and operate the piston or plunger 35.

In Fig. 11, I have shown a second modified form in which one'of the side pier-cs 20 has been recessed at 55 to provide a con-Q 'tainer for lubricant which has a discharge 56 leading to the pump chamber 32-3. The Idischargc from the pump chamber is at 57 to a secondary chamber 58 and from this secondary chamber through the system as above described. The only dill'crcnco botwecn this constriu-tion and tho con tru tion heretofore described is that an enlarged side piece is provided which is cored out to form a receptacle for lubricant.

I have described any invention as pro vided with lubricant passageways leading to the parts oftbe shackle to which the device providelub'icating conduits leadingv from 'to be lubricated the pump to the group of parts to be lubric'ated located in the nnmcdiatc vicinity ot the 'lubricat-nig; device. by this form of construction .i can lubricate the entire chassis and provide luliirication w'th minimum. provision of lubricant passageways and from a minimum number of suitably (lisposed shackles. The parts to be lubricat d are naturally grouped at the four corners of the chassis and in the plan view of Fig. l

I have shown at A lubricating devices so disposed in proximity the shackles located at such points as to be operated therefrom. Dotted lines are used to indicate conduits leading from these lubricating devices t suitably arranged groups of parts in the. vicinit 0t each lubricating device to lubricate such parts from the cored out openings through the shackle members. A suitable conduit such copper tubing could be provided to extend along the lran'ieot the chas-- sis to the next part to be lubricated.-
